WILLIAM S. NI CQLSON, OF SALISBURY, NORTH CAROLINA.

WASHING-MACHINE.

To all whom it may concern: Be it known that I, WILLIAM S. NIOOLSON, a citizen of the United States, residing at Salisbury, in the county of Rowan and State of North Carolina, have invented new and useful Improvements in \Vashing-Machines, of which the following is a specification.

This invention relates to washing machines, the object of the invention being to provide an effective apparatus of this character: for thoroughly and rapidly cleaning goods without possibility of injury thereto.

In the drawings, accompanying and forming part of this specification I show in detail one simple form of embodiment of the invention which, to enable those skilled in the art to practice the same, will be set forth in detail in the following description, while the novelty of the inventlonwill be included in the claims succeeding said description. i

Referring to the drawings: Figure 1 is a transverse sectional view of a washing machineinvolving my invention. Fig. 2 is a longitudinal sectional view of said machine. Fig. 3 is an endelevation of the same. Fig. 4 1s a cross sectional view of vthe outer casing looklng toward the end thereof appearing in Fig. 3. Fig. 5 is an end elevation of the inner drum. I

Like characters refer to like parts throughout the several figures of the drawings.

The machine includes in its make-up an outer or stationary casing 2 which may be of any desirable material or form. The said casing may be of cylindrical shape and it may be made of metal or Wood or a combiration of these materials, as desired. Said casing or cylinder 2 rests upon a framing or bed such as that denoted in a general way by 3, the two parts being united in any desirable manner. The casing 2 is provided with a hinged door or flap t by which access may be had to the interior thereof and which, during the washing operation, is held closed by a latch 5.

Within the casing 2 is mounted an inner cylinder or drum 6 which, in the present case, is rotary. the periphery of the drum or cylinder 6 being separated from the inner surface of the outer casing or cylinder 2 to provide for the thorough circulation of water or other fluid therebetween. The peripheral portion of the rotary drum has a multiplicity of perforations for the pgssage of thewater or other fluid that may lntroduced Specification 0 Letters Patent.

into the apparatus. The inner drum or rotary cylinder 6 is equipped with a hinged door 7 by opening which apparel, clothing, or other goods can be introduced into or removed from said inner drum, the door being held closed by a catch 8.

To aid in the thorough cleansing of the material in the drum (5 I introduce thereinto a fluid preferably under pressure, and this fluid may be of any desirable kind, for example, it may be steam or compressed air, separate pipes being provided to lead either of these substances .into' said drum 6, or one of these pipes-can be utilized for conducting a bleaching gas into the said drum (3. Two of such pipes are shown, one being denoted by 9 and the other by 10. The pipe 9, for example, maybe used for conveying steam, .while the pipe 10 can carry compressed air, each of these agents being received from a suitable source of supply not illustrated. The delivery ends of these pipes 9 and 10 join and from their point of ju'ne ture the pipe 11 extends, the latter constituting what might be considered the main supply pipe or duct, Whilethe pipes 9 and 10 constitute auxiliary supply pipes or ducts.

In the pipe 9 is a valve 12, while the pipe 10 may be furnished with a similar valve 13. By closing the valve 13 and opening the valve 12 steam can be supplied to the apparatus and, by reversing this operation, compressed air can be delivered into said apparatus. I

Within the outer casing or cylinder 2 and on one end thereof is a boss 14, and through said boss and end a spindle 15 projecting from one end of the drum 6 extends, the opposite end of the drum being provided with a tubular spindle or sleeve 16 extending through the opposite end ofthe outer casing or cylinder 2. Into the tubular spindle or sleeve 16 is fitted a stub shaft 17 the two parts being connected together in some sui-table manner by a setscrew 18. The stub shaft 17 isu'epresented as carrying a pulley 19 adapted to be operated by a belt not shown. When the belt is in motion it will be clear that thedrum 6 will be turned. I 'tendingthroughthe bossl t is a port or passage 20, and the pipe 11 is inwardly bentat its lower end,-the inwardly bent portion being tapped into the adjacent end of the cylinder.2 to put said pipe illinto communication with said port or passage 20; 'The port 21 are bent outward, while the delivery ends or passage is located inthe lower part of the boss 14', and the'purposeofthis will here- .inafter ap ear.,

Thaten of the drum -6 which is adjacent' totlhe boss 14 is provided with several radial passages-21 which extend longitudinally of .ribs 22 and the hub portion 23 of the drum 6', said ribs 22, as shown in Fig. '5, being formed on the exterior of the drum 6. --The receiving ends of these passages or-ch'annels' thereof are bent inward, "to deliver fluid, whether it be steam, compressed air, or some other agent, into the ducts 24-within thedrum 6. Said ducts 24 can be formed by 'longitudinal h'ollow ribs or semi-tubes fastened to the inner surface of the drum 6,

: and there may be any desirable number of these semi-tubes or hollow ribs 24. .The semi-tubes or hollow ribs 24 extend from one end of the drum .6 to the other and. in the present case, they are of'approximately V- 'shape in cross section and have in one of boss 14'with substantially af'fluid tight fit.

While I have aplurality of ducts or passages 21, there is in the present case only one supply port 20 therefor, and by virtue of this I am enabled to supply onlyione of the ducts 21 at a time, the parts being soar-ranged that referably I 511 ply through one; of said ducts 21 what is or the time being the lowermost ducti24. It will be assumed that'a fluid is being supplied to thepipe 11 and naturally such fluid fills the passage or port; 20. The entering end of one of the passages or ducts 21 is shown in. register with the port or passage 20, the entering ends of the remaihing passages or ducts 21 being covered by the solid or imperforate inner face portion of the boss 14, whereby the fluid from'the pipe 11 will pass intoonly one otthe passages or ducts 21 which-in the present case would be-that passage or uct 21 which stands vertically below the center of motionof the drum in Fig. 1..' The consequence-of this isv that the'fluid from the pipe 11 passes only into the lowermost duct or longitudinal passage 24 and, emerging from the latter, passes into the interior of the drum 6.

By virtue of the construction hereinbefore described I can thoroughly and quickly remove dirt from'clothing. When the 1nner drum is rotating I force, during such opera- "tion, compressed air, steam, or other flu d ing conduits extendin register with said port.

directly against and through the goods and therefore save time in washing, improve the quality of work, and lessen possibility of injury to the goods. By means of the apparatus I am enabled to pass air or other suitable fluid through the goods below the surface of the water in the-machine. I

It will be clear from what has been herein- I beforestated that each duct or passage 21 and a cooperating duct or passage 24 present collectively a conduit for conveying an agitating fluid'into the interior of the drum 6, and these conduits have a portion movable below the surface of the water in the drum. ,and out-er casing 2.

I wi.h to make it clear that I provide.

ineans whereby I am enabled to direct an agitating fluid, such as steam, air or gas, against and if necessary throughthe clothing in the under portion of a'movably mounted drum or clothes-container. In the present case this result I accomplish by passnot from the sides thereof, whereby effectual cleansing of said clothing can be obtained.

' What I'claim is: i 1 1. In a washing machine, an outer casing, a drum having conduits, each conduit being movable to the lower'portion of the casing, and means for supplying a fluid to the conduits, the machine having means to prevent the flow of the fluid into certain of the conduits while such fluid is being supplied to one of saidoutlets. i

2. In a washing machine, a casing and a movable drum in the casin the drum havfu ly from end to end of the interior t ereofand provided with'perforations opening into the interior of said drum and also having entering ends exterior of the ends of said drum, the casin having a member provided with a ort, an

the drum, on its movement, being a apted to bring the enterm ends of said conduits into 3. In a washing machine, a casing and a.

rotary drum 1n said casing, the drum havin conduits extending transversely and longltudinally thereof, the conduits having perforations o enlng into the interior of 'the' drum, and t e casin having a boss provided with a port throug the" same,jthe entering ends of sa1d conduits being adapted-to successively eglster with said porton the rotation'of the drum. p 4. In a washing mach ne, an outer casln provided 'with an interior boss on one en thereof, said boss havin a port through the.

same, and a rotary per orated drum in the cas ng, the drum having nduits extending .the entering ends of said conduits bein adapted to successively register with sai port and said conduits having perforations in the drum, and the drum having an-annu-- lar flange overlying and turning upon said boss;

'i. In a Washing machine, a casing and a r tary drum in said casing, the drum having at one end thereof a series of radial passages and also having interiorly thereof a series of hollow ribs of substantially V-form in cross section, one side of each rib being perforated and the interiors of the ribs being in communication with the respective passages, the casing having an interior boss provided with a port, and said passa es being adapted to successively register w1th said port on the rotation of the drum.

6. In a washin mach1ne,.a casing, a rotary drum 1n sal casing, the drum having at one end thereof a series oi radial passages and also having interiorly thereof a series of hollow ribs of substantially V-forin in cross section, one side of each rib being perforated and the interiors of the ribs being in communication with the respective passages, the casing having an interior boss provided with a port, and said passages being adapted to successively register with said port on the rotation of the drum, a pipe in connnunica? tion with said port, and other pipes provided with valves, in communication with said first-mentioned pipe.

In testimony whereof 'I have hereunto set my hand in presence of two subscribing Witnesses.
